How to Create a USB flash drive for Ubuntu Installation

Many of my friends know that Ubuntu is a very good Linux release. It is also very easy to download Ubuntu from the official website. But after downloading ISO, how can we install it? Of course, in our early years, we installed the software by recording the DVD. Now, as the optical drive is gradually eliminated by the market, Ubuntu keeps pace with the times like Windows, you can also install the USB flash drive on Ubuntu.

The following describes how to install a USB flash drive in Ubuntu on Windows, Mac, or even Linux.

Ubuntu version Selection

First of all, we need to know that Ubuntu has the LTS version and the "cutting-edge technology version", both of which can be used as daily desktop terminals, but we usually think that the LTS version is more stable, in addition, you can obtain technical support for five years from the date of release. The so-called "cutting-edge technology edition" released between LTS versions only has a nine-month support period. After expiration, users must upgrade to a new version.

Then there is a 32-bit and 64-bit version selection problem. I personally suggest you install the most popular 64-bit version. Of course, if your computer is too old or cannot be supported, install 32-bit. In the past, there was a popular saying that when the memory is smaller than 3 GB, do not select the 64-bit version for installation. In fact, this can be ignored, and 64-bit can make full use of CPU support, even if your memory is less than 3 GB.

Regardless of the version you choose, you can download the ISO installation image from the official website:
